Ah, well, the P2 box that I referenced happens to be running CentOS 5.9. 
  That's a generation earlier than what 5107R is built on, and it's most 
likely that certain architectures have been obsoleted by the Redhat 
development team.

According to this link, a P3 should support PAE:

No.  Pretty much any 64bit CPU from Intel or AMD is compatible with 
5108R.   32bit procs will need 5107R.

I think it's funny you put "duel-core" rather than "dual-core".  I just 
have a picture in my head of CPU's marching 10 paces, turning around and 
shooting each other.    But that aside, pretty much anything with 
multiple cores is also going to be a 64bit proc, so it would be 
compatible (and I would recommend 5108R).

20GB > 2GB.    Although it may be possible to squeeze a basic RHEL (ie 
CentOS, Scientific Linux, etc) into 2GB of space and have some room left 
over, that's an absolute bare minimum requirement for bare minimum 
services.   I don't think you'd be able to comfortably squeeze all the 
required packages for a BlueOnyx system into 2GB and walk away with 
anything usable!

Yes.

What that actually says is "392M CLI/512M GUI", which means it needs 
392MB for a CLI (command line interface) installation and 512MB for a 
GUI (graphical user interface) installation.   Note that BlueOnyx is CLI.

Sorry if I was unclear before, but I mentioned that the P2 box that I'm 
running with that pittance of RAM is actually just handling storage for 
my backups.   It's not a BlueOnyx machine.

The real answer that you are looking for is a set of minimum 
requirements for BlueOnyx.   Here's what I would submit to you as the 
absolute minimum system requirements for BlueOnyx:

Pentium 3 500Mhz or better
512MB RAM or better
40GB hard drive or better

5107R for 32-bit installs, 5108R for 64-bit installs.
